# Start up a X11 virtual frame buffer, export a model to a web page and stop the X11 virtual frame buffer.
# 
# This script is meant to be run from a cronjob.
# Xvfb is a headless frame buffer, which means that a physical graphical display is not required.
# This script requires Xvfb, which is most commonly found under Linux.
# This script *might* work under Mac OS X if Xvfb is installed.
# This script is not likely to work under Windows. 

# Usage:
#   cd $PTII/ptolemy/domains/sdf/demo/MaximumEntropySpectrum
#   $PTII/ptolemy/vergil/basic/export/exportModelX11 MaximumEntropySpectrum.xml
# The directory MaximumEntropySpectrum will contain the html files.
